Hi
@ash, happy to help!
The 1st point is referring to the 10,000 free successful task runs that come with our Standard tier. If you don't exceed 10,000 runs, Standard tier is totally free.
The 4th point is describing our role based access controls that come with the Standard tier. On the Standard tier, users can be permissioned as Administrators, Users, or Read Only Users (also sometimes called Restricted users). You can read a bit more about roles here
